I got my wife an Asus EEE for Christmas - she loves it.  I found it so convenient for quick email or google searches around the house, that I got one as well.  They are only a couple of pounds.  Networked immediately without hassle.

We took a cross country flight in April and both watched individual movies on our own screens.  The batteries definitely outlasted a 4.5 hour flight (Asus claims 7 hours, but I think that's stretching it).

I haven't tried to put Carrara on it, but I'm tempted.

If you get an Asus, there is one oddity to be aware of.  If you immediately upgrade the memory to 2GB (costs about $25 for the memory card) you must enter bios and save.  You don't have to make any changes, but the bios will not see the additional memory until you go in and save.  Rumor has it that Asus agreed not to ship with more than 1GB memory as MS did not want people to have too good an experience on old XP.  Swap out of card is very simple.
